Aerojet Rocketdyne Provides Propulsion for Artemis III Mission and Three Additional Orion Spacecraft

Aerojet Rocketdyne, a California-based aerospace and defense company, recently announced its involvement in the upcoming Artemis III mission to the Moon, as well as its contract to provide propulsion for three additional Orion spacecraft. Let's take a closer look at Aerojet Rocketdyne's role in these important missions.

Artemis III Mission:

Aerojet Rocketdyne will be providing propulsion for the Artemis III mission, which is part of NASA's Artemis program. The Artemis program aims to land the first woman and the next man on the Moon by 2024 and establish a sustainable human presence on the Moon by the end of the decade.

The propulsion system that Aerojet Rocketdyne is providing for the Artemis III mission includes four RS-25 engines and two RL10 engines. The RS-25 engines, which are also used on the Space Shuttle, will provide the main propulsion for the core stage of the Space Launch System (SLS) rocket that will carry the Orion spacecraft and its crew to the Moon. The RL10 engines will provide the propulsion for the Orion spacecraft's upper stage, which will be used to insert the spacecraft into lunar orbit and then return the crew back to Earth.

In addition to the propulsion system, Aerojet Rocketdyne is also providing the engines for the boosters that will assist in launching the SLS rocket.

Three Additional Orion Spacecraft:

Aerojet Rocketdyne has also been contracted to provide propulsion for three additional Orion spacecraft. The propulsion system for these spacecraft will include four Aerojet Rocketdyne MR-104J engines, which will be used for the Reaction Control System (RCS) and the Orbital Maneuvering System (OMS).

The RCS engines provide small bursts of thrust to control the spacecraft's attitude and position, while the OMS engines provide the large bursts of thrust needed to change the spacecraft's velocity and trajectory. The MR-104J engines have a proven track record of reliability and performance, having been used on multiple previous NASA missions.

The Orion spacecraft is a key component of NASA's Artemis program, as it will be used to transport astronauts to and from the Moon. The spacecraft is designed to carry up to four crew members and can support missions lasting up to 21 days.

Aerojet Rocketdyne's involvement in the Artemis III mission and the three additional Orion spacecraft highlights the company's expertise in propulsion systems for space exploration. These missions are critical to NASA's goal of returning humans to the Moon and establishing a sustainable presence there, and Aerojet Rocketdyne's contributions will be vital to their success.
